MOVED COMPOSITION TO BE USED IN THE MANUFACTURE OF SOAP. 'V A The Schedule referred to in these Letters Patent and makingplrt of the some.

To all whom it may concern:

Be itknown that I, Rrcnnnn PJDHOMAs, of the city and county of San Francisco, State of California, have invented an Improved Mode of Utilizing Resinous Substances; and I do hereby declare thattlie agents used in accomplishing the object, together with complete and-- full directions for'iising them, in order to produce the desired result, in the best manner known to me, are

Tlie'object of my invention is to utilize the various resins and resinous substances, such as rosin, the various gums, asphaltum,and coal-tar, by rendering them soluble in water, and thus increasing their availability in the varions-arts-audscieneea To effect this, I: employ silicate of soda, or soluble glass, which, when dilutedrto a certain point and heated, is rendered capable of mixing with the melted resin, so as to form a thickipaste, which, in the case of rosin, is especiallyvaiuable for the. purpose of manufacturing soap, either' with or without theadmixtnre of other substances. p

-I will now proceed to describe minutely my process.

' Oflilicate of soda, otherwise known as soluble glass,

Banm. One hundred (100) parts of this solution are elevated to a temperature of 212 Fahrenheit. From thirty(30) to fifty (50) parts of the resinor gum to be used are then melted and mixed with the hotsilioate, the two combining and forming a sort of paste, which -is soluble in water. This paste may also be miried, in greater or less proportions, with pipe-clay, silica, lime, sulphate of soda, carbonate of soda, soapstone, and simiters. Patent, is

soluble. in water, by combining them with the substances and-in the proportions herein described.
